It's that time of year when shoppers are a little extra on edge due to the holidays. I think it's safe to say that retail workers are feeling the same. When you combine the two, it can be a recipe for disaster...or a brawl in a layaway line anyway. Which is exactly what happened at a Walmart in Sterling Heights.

According to WDIV, the chaotic fight involved a total of four people, a brother and sister who both work at the Walmart and a mother and son who were unhappy with service. The son grabbed a knife from a shelf to scare the workers.

As you can see in the video below, the incident got pretty ugly. I'm not sure exactly what happened but it was enough to cause a fight between the brother and son. For a moment it seemed like everything had cooled down until the son went and grabbed a knife and then came back to the layaway area looking like a madman.

Merry Christmas!
